Girls, hello everyone! Does anyone use similar pads? Our son falls asleep after feeding, I put him in his crib, which doesn't have a pillow, just a mattress. And that's when it starts - crying, wheezing, whining. If I pick him up and hold him, he straight up throws up. If I put myself on a feather pillow, then he's kind of tilted over and sleeps normally ?‍♀️ I don't put the crib pad in the crib naturally, but I don't know what alternative there is. Maybe someone has their own options?
